Probably depends on the course, but at an 11 handicap you may want to consider NOS (new old stock) womens' FIS WC GS skis from the R>23M days. At best I'm getting handicaps a little higher (slower) than you, but I'll switch between Rossi 9GS 19M cheaters and Head iGS 23M skis. I'm much faster on the iGS's but still have a little trouble arcing them when the course is extra turny. On a tight, turny set I will just admit I'm not man enough to turn girl skis, LOL. I'm working on it...
Another option is the Rossi Hero Masters skis:
180 - 21.0 - 114/71/97 - Masters
185 - 23.1 - 113/71/96 - Masters
We have our share of very fast racers in our league- most of the sub-10 handicappers are on slightly older, 'shorter' radius FIS GS skis from before the recent rules changes. ~30 second course for mortals like me, high 20's for the best of us. If your course is shorter with some tighter turns, perhaps the Fischer RC's or Masters from various makes will be best.
